Unfortunately, schools don't pay up front nor at time of delivery but rather 30-60 days after delivery. This would take a whole lot more "out of pocket" money than we are capable of. We are at the seat of our pants as it is. As well, it is a pretty unpredictable when it leaves the shelf. Not a single bottle sold in two months, then all the fix sold in one week. We had to reorder just fix, then the other chemicals sell and all you have is fix. This is just the way it goes for us. Paying as much to ship a case of chemicals as we pay for the case just isn't going to work for us and right now that is the way things were going. So far I am happy with the results from Clayton and we may turn that corner.
